application 'tiled .lune 23, 3924. Serial No. 723746.

To all whom zii' may concern."

Be it known that we, lisnLoN E. Larnn, a citizen of the United States, residing at Houston, in the county ot Harris and State of Texas, and SAMUEL N. HALL, a citizen of the United States, residing at South Pasa.- dena, in the county or Los Angeles and State of California, have invented a new and useful Means for Facilitating the 'Removal or Bise assembling of Rotary Pump Mechanism, of which the following is a speciiication.

rlfhis invention relates to the art of rotary pumping mechanism and refers particularly to certain modiications in the mechanism whereby a novel method of disconnecting' Acertain parts of the same may be employed, and also to the method of disconnecting the parts.

After a rotary pumping mechanism has been assembled in position for elevating liquid from a Well7 such as a water Well, and it has been desired to ldisconnect the stub shaft ot' the motor or other means employed for driving the .vell from the pump shaft of the mechanism, this operation performed in the customary manner has been .extremely diliicuit and expensive.

This invention has for its primary objects to provide a simple method for assembling and disconnecting certain parts of the rotary pump mechanism, and to provide a pump mechanism in which such method of assembling and disconnecting the parts may be readily employed.

rl`he various further objects and advantages of the. invention will bereadily apparent from a description of a preferred torni ot' rotary pump mechanism embodying the invention and of thc method of assembling and disconnecting the parts therefrom.

Reference is made to the accompanying drawings illustrating a rotary pump mechw anism and method of disassembling the same, in which:

Figure l is an elevation of the mechanism, partially in vertical section.

i 13 is suppaortedupon the casing head Fig. 2 is a similar elevation of the upper part of the mechanism, likewise partially in verticalsection, showing the mechanism in the process of assembling or disconnection.

Referring to the drawings, the rotary pumping mechanism embodies a pump l ada ted to be suspended in a vvell by its disc large casing'2 which extends vertically from the pump to the top ot' the Well and there terminates in a casing head 3, which connect-s With a line i into 'which the fluid of the well is discharged. The pump 1 is of the customary impeller-actuatcd type having one or more impellers 5 keyed to a sec. tional pump shaft G `which extends vertically from the bottom upto the top of the Well and is there connected to a stub shaft 7 of' an electrical motor 8 or other driving means; the .pump'shatt Gbemg located concentrically Within the discharge casing 2 and en-.

closed by a shaft casing 9, likewisel pref-4 erably in section` which provides bearing blocks l() engaging the shaft 6 at intervals Abetween the pump and `casing head 3.

'ln addition to the opening communicating with the line Ll, thecasing yhead 3 is provided with an additional opening 10, normally closed by a plug 1l or other means, which'opcning 10 is preferably on the opposed side of the casing head' 3 to which the line Ll connects, and located about the center of the casinghead 3. i

The motor 8 or other driving member is preferably supported on thc casing head 3 by a stand 1Q, thus being spaced somewhat above the top of the casing head 3. The upper section of the shaft casing 9 terminates Within or closely adjacent to the casing head-3 and there connects with a packing box 13 which also provides a cap or closure for )art ofthe upper side of thc casing head 3; tie packing box 13 having an annular flange 14 at. its upper end by which the box The packing' ox 13 is threaded to the exterior of the upper section of shaft casing 9, as

indicated utvl, and is provided with e. cham ber 16 adjacent thereto. Above the chem her 1G the paciring box iii serves to support packing materiel l? surroundiiu,T the stub shaft Tof the driving," member' El, which packing materiel is pressed downwerd withn in the packing box by n, stuffing gland l@ threaded thereto.

l!) indicates un oil duct extending Ver ticnlly through the bos lwhich is conneeted to n lubricant leed cup 2() which may Abe employed for feeding; oil down through the box 13 so that -the oil muy-lion' down the shaft casing in order to lubrieete the beering blocks l() thereol. ii second oil duct Ql'eommunieates with the center out the puchn ing material 'i7 and may be fed with lubricent through the line 22.

The stub shaft v7 ,and pump shaft 6 of the mechanism are oi such length thnt they couple together et o, point 'within the casing heed 3,'3 coupling 'being employed for this purpose, which couplingl preferably has its upper end exteudinzig nbove the top of the npperi section ol' shutt casing 9 end is provided with one or more notches or other similar menus 2l on its upper face by which engsgen'ieut may ube mede with n wrench for the vpurpose hereinafter described. Between the tace and ends of the stub shaft 7 and pump shaft (3 of the meehnnism there is placed on e. spacer .25,-

of the requisite thickness, so that when the shafts 7 and 6 ere forced thereegeinst, the

impellers 5 in the pump 1 'will berproperly centered Within the pump mechanism, such spacers 25 preferably being' provided with a threaded opening 26.

2l', indicates e lug extendingoutwerd iron near the upper end. of the shaft casing 9,

ywhich lug is adapted to be brought in engagement with e stop 30 fixed to the discharge using L) to prevent the slui'ft casing S) l'ro-i'n turningA during fortuin disnssemhlmg operations ou the piunp 1inochenism.` i

W'ith n rotary pump mechunism es herein described, the motor or other driving mem ber 8 may readily be disconnected by removing the plufz 1l in the casing heed o; also removing` the oil .line und leed cup 20 and associated ports from the upper end of the pecking box 12E. The pecking' box i3 is then readily disconnected or screwed upward `i'rom the upper section or the shaft casing, the lug;7 27 und stop SO preventing improper urotation ol' the shulft cosine' during its disconnectinpr step. The packing box is then pushed i'urllwr upward ulonp; the stub slurit T oi the motor und held up by any suitable menus. such ns u prop li placed with one end resting upon the top of the crisinfg houd 3 und the other supporting thebm: 13 Yfrom its nnnuliu' lienges i4. In this position. the coupling; .4, between the pump shui't (i und stub :shui't T is held by n.

immer Wrench 32 and. the drive shaft 7 then re# versed to breuk connections with the cou pling. 4The stand l2 and motor 8 then may be removed it desired.

lt is thus seen that We here provided a simple manner ot assembling; and disussembling certain partsot the pump appa` rntus. This assembling,Y and disassembling oi the apparatus isirequently necessary to properly center or align the impellc-,rs 5 in the pump l, such aligning being determined by the thickness of the spacer between the stub she'tt 7 and the pump shaft 6. The threaded aperture 2G permits bolts or other devices to make engugement with the Washer in removing the spacer Q5 'from .the coupling- 23 when it is desired lo replacev such soccer with e spacer of diilerent thickness.

While the method end means herein described are well suited for the purposes ofthis irwention, the invention is not limited lo details of the method or mechanism hi rein Iset forth, but is ot the scope set forth in the appended claims.
